2016-05-26zebra: use SA_SIZE for RT_ROUNDUP on FreeBSDDavid Lamparter
FreeBSD provides SA_SIZE (and none of the other options to infer padded size of a struct sockaddr). Just define SAROUNDUP to SA_SIZE if it is available. This also drops a superfluous-looking extra macro branch which would require ROUNDUP. It seemed redundant to my eyes, but I have no idea what odd things might have triggered addition of this in the first place...

2016-05-26Fix alignment assumptions on non-RT_ROUNDUP platforms.Greg Troxel
The comment said that apple uses int and BSD traditionally used long, but the code was backwards. This fixes apple to be int, and otherwise long. That should make FreeBSD, which aligns to long, work correctly, even without using SA_SIZE. (cherry picked from commit 941789e470199df4f612368f669ecc0fd096fb9a)

Use the platform-provided RT_ROUNDUP macro to align sockaddrs on the routing socket, rather than using hard-coded assumptions about alignment. Emit a warning if the OS doesn't define alignment macros. Resolves failure of ripngd on NetBSD 6 i386, which changed alignment to uint64_t from long.

2015-10-30zebra, lib/memtypes.c: the netlink sockets work per VRFFeng Lu
This patch lets the netlink sockets work per VRF. * The definition of "struct nlsock" is moved into zebra/rib.h. * The previous global variables "netlink" and "netlink_cmd" now become the members of "struct zebra_vrf", and are initialized in zebra_vrf_alloc(). * All relative functions now work for a specific VRF, by adding a new parameter which specifies the working VRF, except those functions in which the VRF ID can be obtained from the interface. * kernel_init(), interface_list() and route_read() are now also working per VRF, and moved from main() to zebra_vrf_enable(). * A new function kernel_terminate() is added to release the netlink sockets. It is called from zebra_vrf_disable(). * Correct VRF ID, instead of the previous VRF_DEFAULT, are now passed to the functions of processing interfaces or route entries.

2015-05-19Multi-Instance OSPF SummaryDonald Sharp
——————————————------------- - etc/init.d/quagga is modified to support creating separate ospf daemon process for each instance. Each individual instance is monitored by watchquagga just like any protocol daemons.(requires initd-mi.patch). - Vtysh is modified to able to connect to multiple daemons of the same protocol (supported for OSPF only for now). - ospfd is modified to remember the Instance-ID that its invoked with. For the entire life of the process it caters to any command request that matches that instance-ID (unless its a non instance specific command). Routes/messages to zebra are tagged with instance-ID. - zebra route/redistribute mechanisms are modified to work with [protocol type + instance-id] - bgpd now has ability to have multiple instance specific redistribution for a protocol (OSPF only supported/tested for now). - zlog ability to display instance-id besides the protocol/daemon name. - Changes in other daemons are to because of the needed integration with some of the modified APIs/routines. (Didn’t prefer replicating too many separate instance specific APIs.) - config/show/debug commands are modified to take instance-id argument as appropriate. Guidelines to start using multi-instance ospf --------------------------------------------- The patch is backward compatible, i.e for any previous way of single ospf deamon(router ospf <cr>) will continue to work as is, including all the show commands etc. To enable multiple instances, do the following: 1. service quagga stop 2. Modify /etc/quagga/daemons to add instance-ids of each desired instance in the following format: ospfd=“yes" ospfd_instances="1,2,3" assuming you want to enable 3 instances with those instance ids. 3. Create corresponding ospfd config files as ospfd-1.conf, ospfd-2.conf and ospfd-3.conf. 4. service quagga start/restart 5. Verify that the deamons are started as expected. You should see ospfd started with -n <instance-id> option. ps –ef | grep quagga With that /var/run/quagga/ should have ospfd-<instance-id>.pid and ospfd-<instance-id>/vty to each instance. 6. vtysh to work with instances as you would with any other deamons. 7. Overall most quagga semantics are the same working with the instance deamon, like it is for any other daemon. NOTE: To safeguard against errors leading to too many processes getting invoked, a hard limit on number of instance-ids is in place, currently its 5. Allowed instance-id range is <1-65535> Once daemons are up, show running from vtysh should show the instance-id of each daemon as 'router ospf <instance-id>’ (without needing explicit configuration) Instance-id can not be changed via vtysh, other router ospf configuration is allowed as before.

2013-01-16zebra: fix sockaddr_dl length assumptions (BZ#737)David Lamparter
Quagga makes bad assumptions about sockaddr_dl (on NetBSD, but possibly on other systems as well). Particularly, sizeof(struct sockaddr_dl) returns a size that does not include the full sdl_data field, leading to not enough data being copied. This breaks IPv6 RAs in particular, as a broken mac address from sockaddr_dl will be included in the packets.

2012-11-05build: check actually-used BSD link state fieldsDoug VanLeuven
ifi_link_state missing in OS X. There could be other *BSD's that haven't implemented it and possibly affects older implementations. The existing HAVE_BSD_LINK_DETECT configure.ac check is only confirming the link state detection using ifmediareq.ifm_status found in <net/if_media.h>. This is the link state detection used in zebra/ioctl.c. Later, *BSD redefined struct if_data in <net/if.h> and included link state detection. This is the method used in zebra/kernel_socket.c Additional test defined in config.ac to test for member struct if_data.ifi_link_state defined in <net/if.h> separate from test for <net/if_media.h> ifmediareq.ifm_status Fixed #ifdef's in zebra/kernel_socket.c to use the new #define No impact on older function calls in zebra/ioctl.c Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using gcc & clang.

2012-11-05zebra: kernel_socket: fix overflow in RTA_ADDR & RTA_ATTRDoug VanLeuven
In zebra/kernel_socket.c, copying sockaddr from *_msghdr: There are really 2 different lengths that need to be determined. 1) the length required to point to the next sockaddr in the mesg buffer which might include any required padding and 2) the actual length of the sockaddr data that needs to be copied into the destination field. They may or may not be the same value. Sizeof sockaddr_in6 is 28, which to pad for alignment purposes on 32 bit systems with a long of 4 bytes is evenly divided and requires no padding. On 64 bit systems, with a long of 8 it is padded with 4 extra bytes.So the current RTA_* macros are copying 32 bytes into a 28 byte field on 64 bitsystems, where the field overflow did not occur on the 32 bit systems. Since using sa_len required the use of an #ifdef which couldn't be used directly inside a #define, it made sense to move the copy into the function to allow typdef checking throughout and eliminate the hack to suppress compiler warnings. Fixed declaration of cp in ifm_read after compiler noticed type mismatch.

In OS X 10.7 zebra crashed on invalid execution address. sockaddr padding in *_msghdr is observed to be 4 bytes in 64bit OS X. The ROUNDUP macro assumed alignment on sizeof(long) which allocates 8 bytes on 64bit systems, 4 bytes on 32bit systems which is true for BSD generally. Test for Apple and use sizeof(int) which allocates 4 bytes on 32 & 64bit systems.

Comment now shows the new interpretation of the destination addr: if ZEBRA_IFA_PEER is set, then it must contain the destination address, otherwise it may contain the broadcast address or be NULL. (CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete macros that were specific to IPv4 and not fully general. (CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag. (CONNECTED_PREFIX) New macro giving the prefix to insert into the RIB: if CONNECTED_PEER, then use the destination (peer) address, else use the address field. (CONNECTED_ID) New macro to come up with an identifying address for the struct connected. * if.c: (if_lookup_address, connected_lookup_address) Streamline logic with new CONNECTED_PREFIX macro. * prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros for better performance than the general prefix_copy function. * zclient.c: (zebra_interface_address_read) For non-null destination addresses, set prefixlen to equal the address prefixlen. This is needed to get the new CONNECTED_PREFIX macro to work properly. * connected.c: (connected_up_ipv4, connected_down_ipv4, connected_up_ipv6, connected_down_ipv6) Simplify logic using the new CONNECTED_PREFIX macro. (connected_add_ipv4) Set prefixlen in destination addresses (required by the CONNECTED_PREFIX macro). Use CONNECTED_PEER macro instead of testing for IFF_POINTOPOINT. Delete invalid warning message. Warn about cases where the ZEBRA_IFA_PEER is set but no destination address has been supplied (and turn off the flag). (connected_add_ipv6) Add new flags argument so callers may set the ZEBRA_IFA_PEER flag. If peer/broadcast address satisfies IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning. Set prefixlen in destination address so CONNECTED_PREFIX will work. * connected.h: (connected_add_ipv6) Add new flags argument so callers may set the ZEBRA_IFA_PEER flag. * interface.c: (connected_dump_vty) Use CONNECTED_PEER macro to decide whether the destination address is a peer or broadcast address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT). * if_ioctl.c: (if_getaddrs) Instead of setting a peer address only when the IFF_POINTOPOINT is set, we now accept a peer address whenever it is available and not the same as the local address. Otherwise (no peer address assigned), we check for a broadcast address (regardless of the IFF_BROADCAST flag). And must now pass a flags value of ZEBRA_IFA_PEER to connected_add_ipv4 when a peer address is assigned. The same new logic is used with the IPv6 code as well (and we pass the new flags argument to connected_add_ipv6). (if_get_addr) Do not bother to check IFF_POINTOPOINT: just issue the SIOCGIFDSTADDR ioctl and see if we get back a peer address not matching the local address (and set the ZEBRA_IFA_PEER in that case). If there's no peer address, try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set. * if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl without bothering to check the IFF_POINTOPOINT flag. And if no peer address was found, just try the SIOCGLIFBRDADDR ioctl without checking the IFF_BROADCAST flag. Call connected_add_ipv4 and connected_add_ipv6 with appropriate flags. * if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to connected_add_ipv6. * kernel_socket.c: (ifam_read) Must pass new flags argument to connected_add_ipv6. * rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2 to determine local and possible peer address (so there's no longer a test for IFF_POINTOPOINT). Set ZEBRA_IFA_PEER flag appropriately. Pass new flags argument to connected_add_ipv6. (netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast to determine whether the connected destination address is a broadcast address. * bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete) Simplify logic by using new CONNECTED_PREFIX macro. * ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix, ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX macro. * ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX macro, both options collapse into the same code. * ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new CONNECTED_ID macro. (ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX macro. * ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro instead of testing the IFF_POINTOPOINT flag. * ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro instead of testing with if_is_pointopoint. And add commented-out code to implement alternative (in my opinion) more elegant behavior that has no special-case treatment for PtP addresses. (ospf_network_run) Use new CONNECTED_ID macro to simplify logic. * rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID macro to simplify logic. (rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does not give a useful result if prefixlen is 32 (we require a peer address in such cases). * ripd.c: (rip_update_interface) Fix same bug as above.
